Test a price change on one product or a small collection before applying it more broadly. Creating a task changes real Shopify prices; there is no preview that calculates changes without applying them.
The example below raises a product's price by 10%. For a temporary promotion, use a sale instead.
Run a small test
Open Tasks in Bulk Price Editor.
Click Create task.
Under Price, choose Increase price and enter
10percent.Leave Compare at price and Cost per item unchanged, with No rounding for each field, unless you intend to change them too.
Under Apply to, choose Selected products and select your test product.
Review the selected products and price settings.
Click Create to run the task.
A product priced at 100 becomes 110 before any optional price-ending adjustment. The change applies to the selected product's variants.
Check the result
Open the task's Details to inspect the recorded old and new prices. Check the product in Shopify and on your storefront as well.
Product prices and fixed market prices are different. If the storefront is showing a market with fixed prices, changing the product's base price may not change the price you see there.
Large selections take longer. Use the progress and details to see whether the operation is still working; changing your Bulk Price Editor plan does not increase Shopify's API speed.
Undo the test before running it again
Open the completed test task's Details.
Check whether manual edits, other tasks, or sales changed the test product after the test. Rollback can overwrite those later changes. Continue only if you intend to restore the recorded pre-test prices.
Click Rollback.
Wait for restoration to finish and check the original prices.
Create the larger task with the intended settings and selection.
If you leave the test in place and include that product in another 10% increase, 110 becomes 121. The second task starts from the current price.
